Heir Hunters is a BBC television programme focusing on attempts to find missing or unknown heirs, entitled to deceased people's estates before the British Treasury lawfully collects the money. The show follows the work of Probate researchers from a number of different firms to show how the results of time-consuming research turned out. The main firms followed have been Fraser and Fraser, Celtic Research and Finders International.

It was announced in 2011 that Heir Hunters would run in both BBC One daytime and in primetime television on BBC Two that autumn.[1] The ninth series began airing on BBC One on 23 February 2015.

The series ran as part of BBC One's weekday lineup in the early morning factual slot (9:15 am – 10:00 am), alongside shows including Animal 24:7 and Helicopter Heroes. The second series had record viewing numbers for the time slot and beat the The Jeremy Kyle Show on ITV consistently during its run, prompting the BBC to immediately recommission a third series.

The title cards for the 2008 and later series spell 'Heir Hunters' as 'H£ir Hunt£rs', using the pound sterling sign as a capital E. In each programme of the first two series three unclaimed estates from Bona Vacantia are mentioned in the hope of information being given by a viewer which could help find an heir or heirs. One of these mentioned in the first series resulted in information that led to some heirs being found for an estate.

The term "Heir Hunter" has become known to refer to any person or firm who tracks down beneficiaries to estates of deceased persons. "Heir hunters" may also be known as probate genealogists, probate researchers, heir searchers, or forensic genealogists.

Heir Hunters are unregulated in the UK [2] although STEP (the Society of Trust and Estate Practitioners) have endorsed their use.[3]

In 2011, it began to be transmitted on the History Channel in the UK, New Zealand and Australia.

From 21 November – 2 December 2011, ten re-versioned episodes of series 5 were shown on BBC Two at 7pm each weekday. The expanded episodes have an increased duration of 59 minutes and feature Lisa Faulkner on camera for the first time interviewing experts and Heir Hunters. BBC Two had ordered 20 episodes in total the 2nd set of 10 were from series 6 and were aired in January 2013.
